What the National Weather Service wrote
A spotter measured 7 inches of snow in Thermopolis.
The wider storm
A combination of a cold front moving across the area, lee side cyclogenesis and powerful jet dynamics produced heavy snow across many portions of Wyoming. The snow hampered holiday travel in many areas. The worst conditions were across Johnson County where blizzard conditions developed and Interstate 90 was closed for several hours during Christmas Day. West of the Divide, the heaviest snow fell across the Jackson Valley where many areas had a foot of new snow. Meanwhile, East of the Divide the heaviest snow fell from Riverton and Worland to Casper where from 6 to 10 inches of new snow fell.
